Puy De Lassolas
The Puy de Lassolas ( oc, L'Assolelhat, the sunburnt ountain is a volcano in the Chaîne des Puys in France, peaking at 1187 metres. It forms, with the Puy de la Vache, a group of volcanic craters. Together, they thus form two half craters. Their lava Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or un ... flows created several lakes by crossing valleys, including Lake Cassière to the north and Lake Aydat to the south in the Veyre valley.

Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Chaîne Des Puys
The Chaîne des Puys () is a north-south oriented chain of cinder cones, lava domes, and maars in the Massif Central of France. The chain is about 40 km (25 mi) long, and the identified volcanic features, which constitute a volcanic field, include 48 cinder cones, eight lava domes, and 15 maars and explosion craters. Its highest point is the lava dome of Puy de Dôme, located near the middle of the chain, which is high. The name of the range comes from a French term, ''puy'', which refers to a volcanic mountain with a rounded profile. A date of 4040 BCE is usually given for the last eruption of a Chaîne des Puys volcano. An outstanding example of plate tectonics in action and continental rifting, the Chaîne des Puys region became a UNESCO World Heritage Site in 2018. Formation The Chaîne des Puys is located on the Limagne fault, a major part of the European Cenozoic Rift System which formed during the creation of the Alps roughly 35 million years ago. The region h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puy De La Vache
Puy () is a geological term used locally in the Auvergne, France for a volcanic hill. The word derives from the Provençal ''puech'', meaning an isolated hill, coming from Latin ''podium'', which has given also ''puig'' in Catalan, ''poggio'' in Italian, ''poio'' in Galician and Portuguese. Most of the puys of central France are small cinder cones, with or without associated lava, whilst others are domes of trachytic rock, like the of the Puy-de-Dôme. The puys may be scattered as isolated hills, or, as is more usual, clustered together, sometimes in lines. The chain of puys in central France probably became extinct in late prehistoric time. Other volcanic hills more or less like those of Auvergne are also known to geologists as puys; examples may be found in the Eifel and in the small cones on the Bay of Naples, whilst the relics of puys denuded by erosion are numerous in the Swabian Alps of Württemberg, as pointed out by W. Branco. Sir A. Geikie has shown that the puy typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Crater
A volcanic crater is an approximately circular depression in the ground caused by Volcano, volcanic activity. It is typically a bowl-shaped feature containing one or more vents. During Types of volcanic eruptions, volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava. A volcanic crater can be of large dimensions, and sometimes of great depth. During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera. Geomorphology In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form. Other volcanic craters may be found on the flanks of volcanoe ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Cassière
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Aydat
{{PuyDôme-geo-stub ...
Lac d'Aydat is a lake in Aydat, Puy-de-Dôme, France. At an elevation of 837 m, its surface area is 0.65 km². It is suggested by some historians that it is the site of Avitacum, the location of the villa belonging to the fifth-century senator and bishop Sidonius Apollinaris, as described in detail in one of his letters.''Epistulae'' II.2 as discussed in C. E. Stevens (1933) ''Sidonius Apollinaris and his Age'' Oxford: Clarendon Press, Appendix B, p. 185.

Veyre Valley
The Veyre is a left-bank tributary of the river Allier in the French region of Auvergne-Rhône-Alpes. Geography The Veyre is long. It has no concrete source given that it originates at the plateau des Monts Dore, from the confluence of two streams : la Narse et le Labadeau which begins at the Puy de Vedrine. La Veyre has the particularity of having had its flow breached around 10,000 years ago by a lava flow of the Puy de la Vache and the Puy de Lassolas which formed a volcanic reservoir, the lac d'Aydat. Shortly after the lac d’Aydat, the Veyre then disappears underneath the volcanic heath of la cheire d’Aydat, then reappears downstream of Saint-Saturnin. At Veyre-Monton, between Tallende and Veyre, it is joined by the Monne. It flows into the Allier at Les Martres-de-Veyre Les Martres-de-Veyre (, literally ''Les Martres of Veyre''; oc, Las Martras) is a commune in the Puy-de-Dôme department in Auvergne in central France.
